I won a plant at a club meeting and I thought it was a cactus. It has a tag which says hens and chicks. But it is named 'cobwebs' on the tag. It looks like it has fine hairy looking 'stuff' on it. I need to know if it will hurt my son if he touches it? Hopefully, he won't. but in the event he decides to grab it and dump it out all over, will it hurt him? If it will, I need to rehome it. My son is 19 but he is mentally handicapped and once in a while he has mishap with houseplants, so I don't normally keep many of them.
I tried looking it up in the database but couldn't find it.

That maybe Sempervivum arachnoideum, it forms those cobweb-like fine white threads. Not a cactus, it has no areoles that has thorny spines.

This is my plant when I first had it in March 2013: they are actually cute, if they get to multiply and form a mound. Your son might find it interesting to pull the new babies as it forms though. Smiling

Editing to add this other photo of my other semp arachnoideum before, more tight, mounding type growth, it came from a very small container before, so it looks less flat , but it still has the cobweb-like hair at the center of each rosette:

Hi Frillylilly. Can you take a photo for us? We certainly don't want your son to be injured. And if it is a sempervivum (Hen & Chicks) the best place for it is outdoors.
Have you tried touching the rosettes?

Great photos tarev.

No I am scared to touch them! I will try to take a photo tomorrow and post it.

Tarev, I think mine look taller, instead of short/squatty like yours, but it is hard to id from a photo. The cobwebs look like yours though.

Tall?? Hmm..better post a photo then..hens and chicks are typically growing in rosette form, unless it is an echeveria which often times gets dried out lower leaves that exposes a neck/stem.

Could it be an "Old Man" cactus? It's also known as Grandpa cactus. Check out the plant data base.

Hi Frillylily also if it is truly a sempervivum - they are not poisonous to humans, even if they are eaten, in small amounts. They used to make skin tonics using these plants. So totally safe to touch.
But like other's have said a picture with help the most for us to guess what it is!
If it is a catcus, they too can have soft fuzz on them, if you touch it gently you won't get pricked.
The fuzz on a sempervivum will be soft though and not prickly Thumbs up
Best to you! I tip my hat to you.

Right now it is about an inch and a half tall, but they are not even rooted well, just kinda sitting on the soil.

They look cute! Thanks for the photo! Yup, those are semp arachnoideums. Somehow the tall growing ones seems to be preparing to bolt, meaning to make some blooms.

This is what my semp arachs did when it went bolting, late Spring 2013, so when it starts to do that, buds, blooms..then bye bye plant, sadly it is monocarpic but you can try harvest seeds later Smiling

Frilly - these are super easy plants, except that they don't want to be too wet! Depending on what your winter is like (if it isn't too many days in a row of below freezing temps) then you can put them outdoors in a sunny spot under an ever or somewhere they won't get too much rain! Otherwise a windowsill until spring is here! Thumbs up

well they don't seem mature enough to bloom, they look like they are just little starts that were just put in this pot recently. Do they even get roots at all,? maybe they are supposed to just kind of sit on the soil like that? I can't tell they are attached to the soil hardly. The pot btw is about 2inx2in so these are really little. I have it in a north window now, just moving it around the house to get sun but not too much. So these should live outside in zone6? The tag doesn't say if they are hardy, just assumed it wasn't. I may try putting it outside for the summer and see how it does. If it increases and grows well I may try leaving it next winter. Are all the semps cold hardy?

They are alpine succulents, so they can take the cold but preferably not too much rain, but my growing area is different. Here it is at its happiest during our mild winters, and suffers big time when we go back to our hot and dry warm days and into summer.

I would imagine someone uprooted it from their own collection and put it in that little container to be given away during your club meeting. It does make roots, but they are rather shallow, so it does not really need big containers. But they will really enjoy better growing outdoors as already mentioned.

They are fun to grow, if my growing conditions are really ideal for it, I would plant more of it. Smiling

Frilly, sempervivum are alpine plants that live in high elevations with lots of snow during winter. And they require at least 1/2 day of sun. Unless you live in an area that has very hot and harsh summers. Then the would need filtered/dappled sun/shade.
Right now it would probably do better in a very cool room/garage, or a covered deck/porch. Like Greg suggested. Just give it sips of water, don't over water.
The three rosettes at the bottom right corner look good and should produce many offsets for you this year. The other two will bloom and die. Many things can trigger blooming, stress, age, etc. Many of the arachnoideum types of sempervivum stay small, as you can see in tarev's excellent photo in her above post.
I see it has the name of 'Cobwebs' on the nursery label. That is not a correct cultivar name, just a descriptive name they gave it.

You are going to love your little Sempervivum arachnoideum. I can't wait to see updated photos as it starts producing little chicks surrounding the hen. Hurray!

In the Winter I'd let them get as much sun as possible indoors. If inside they won't know it's Winter and they'll try to grow and they'll need sunlight for that or else they'll get leggy and weak.

ok, guys! Thanks for the id and the tips. I really appreciate it.
I have not watered it much, cause I knew whatever it was it wouldn't like water. I am going to plant it outside later this year, so now that I know it is cold hardy, the prickly hair thing won't matter anyway! I just didn't want to have it in my house around the kids if it was unsafe. Will post updates as they come....

Thank You!

About water, you are correct to be cautious, but this is not a cactus. If the soil is dried out then moisten it conservatively. Not so much that water comes out the bottom, but enough that the water soaks down into the soil. This plant may have almost no roots, which is OK. But it it will need to grow new roots and get established, and moisture will help out with that. But go ahead and let it dry out between the occasional waterings. Too much water is more often the problem than not enough.
